Glass envelope power diode 6D22S / 6Д22С ORION RADIO "NOS"

6D22S RADIO ORION "NOS" 9-pin, 6.3V. Made in Yugoslavia

6D22S is a glass-envelope power diode for use as a half-wave. Its warm-up time is longer than that of common rectifier tubes (such as the 5AR4/ GZ34), making it an excellent, rugged power-on delay device for audio amplifiers. Its high pulse current capability gives sound quality which is superior to commonly-used rectifier tubes.
